Usage

waterStress(gdx, stressRatio = 0.4, file = NULL, level = "cell")

Arguments

gdx	GDX file
stressRatio	threshold defining level of water stress (e.g. 0.2 for medium water stress, 0.4 for high water stress)
file	a file name the output should be written to using write.magpie
level	spatial level of aggregation: "cell" (cellular), "reg" (regional), "glo" (global), "regglo" (regional and global)
